In the end, Napoli managed to win today, with Anguissa scoring the winning goal in the 95th minute. Cagliari failed to force the reigning Serie A champions to share the points, they were very unlucky. The narrow victory was enough to secure three points, even if it came late, but Conte certainly isn't happy with his team performance. Without Lukaku, Napoli attack looks blunt and struggles to score, and I think this might continue to make it difficult for them to win in the future.
Conte should be happy that his team managed to secure 3 points in the game after a very good performance but nothing to show for it until the added time when A. Zambo Anguissa got the only goal of the game to put Napoli ahead, Cagliari was more of defensive in the game because they couldn't face Napoli as Napoli was in total control of the game but the absence of a finisher for the Napoli team keeps affecting them not to score goals. The presence of Lukaku is missing in the team and it's going to affect them more if Napoli play against a very strong opponent that has good attackers in the team.
